To all whom it may concern:

Be it known that I, EMILIO MUJIoA CANTO, lieutenant-colonel in theChilean army, and a citizen of the Republic of Chile, residing atSantiago, Chile, have invented certain new and useful Improvements inRailway Rolling-Stock, of which the following is a specification,reference being had therein to the accompanying drawings.

My present invention relates to improvements in railway rolling-stock;and the main object of my invention is a provision whereby the wheelscarried by the locomotive or cars are so mounted as to revolveindependently, so that there is no danger of the axle breaking inrounding curves and which are so constructed as to bring the body of thecar relatively lower to the rails, and thus bring the center of gravitynearer the surface.

IVhere my invention is applied to locomotives, the fire-box area isgreatly increased, as it can be extended farther forward withoutinterfering with the axle of the drivewheels, and thus greatly assistingin the capacity for generating steam.

There the invention is applied to cars where the trucks in general useare employed carrying from four to six wheels, I simply use two wheels,each one of which is independently journaled, and where the cars are ofextra length I provide a third set of wheels arranged centrally of thecar, said wheels being flangeless or smooth, so as to have a lat eralmovement as the car rounds curves and at the same time receiving thecentral weight of the car, these central wheels being connected with anintegral axle, as the twisting motion on the smooth-surfaced wheelsis'not so great as on the flanged wheels, where the flange abuts theside edges of the rails in rounding the same.

Another object of my invention is to provide a means whereby the wheelsare guided while rounding the curves and also a means whereby each Wheelis properly oiled and the oil retained, so as to not render it necessaryto continually supply the wheels with oil, which in the old form ofbearing is continually wasted instead of being economically used.

Another object of my invention is to so mount the wheels that the weightof the car is suspended upon the axle in each individual wheel insteadof, as in general use, having a bearing-down weight, this means ofmounting allowing the car-body or locomotivebody to assume a positionlower to the rails than is the case in general use.

To attain these objects, my invention consists of a new and novelarrangement for railway rolling-stock embodying novel features ofconstruction and combination of parts, substantially as disclosedherein.

In the accompanying drawings, Figure 1 is a side elevation of alocomotive equip ed with my invention. Fig. 2 is a bottom p an viewthereof. Fig. 3 is a side elevation of another form of a locomotiveequipped with another form of my invention. Fig. 4 is a bottom plan viewthereof. Fig. 5 is a side elevation of an open tramway-car embodying myinvention. Figs. 6, 7, 8, and 9 are views of the car and its frame asemployed on locomotives or cars, as may be desired. Fig. 10 is a sideelevation of a railway-car embodying my invention and having the centralwheels. Fig. 11 is a bottom plan view thereof. Figs. 12, 13, and 14 aredetail views of a construction of wheel with means for assisting thesame in rounding curves. Fig. 15

is a side elevation of a modified construction of frame and the wheel tobe used in connection with the curved rounding device. Figs. 16 and 17are detail constructions of a modified form of invention for assistingthe wheels in rounding curves. Figs. 18, 19, and 20 are detail views ofthe oil device used in connection with the wheels.

Referring to the drawings, and more particularly to Figs. 1 and 2thereof, the'numeral 1 designates the locomotive-boiler; 2,. thefire-box; 3, the cylinder, and 4 the connecting-rods operated upon bythe piston 5. The entire locomotive is supported on the beams 6 throughthe medium of the heavy springs 7, the beam 6 with the cross-pieces 8forming a platform or frame. Connected to the cross-pieces 8 andparallel with the beams 6 are the inner beams 9 and 9 which form, bymeans of the long cross-pieces 10 and the. short pieces 10", receptaclesfor the flanged wheels 11 and the smooth-surfaced wheels 12, the wheels11 and 12 being connected to the connecting-rod through the medium ofthe cranks 13, so that they will revolve in unison and form thedrive-wheels of the locomotive. The wheels 12 are connected together, asclearly shown in Fig. 2, by means of the axle 14, while the wheels 11are journaled upon the short axles 15, whose ends are mounted,respectively, in the bearings carried by the standards'16, the saidstandards being arranged in pairs and carried by the beams 6 and 9,respectively. The wheels 12 are also provided with the pairs ofstandards 17, so that each Wheel has a bearing upon both sides thereofinstead of only on the ends of the axle, as is the case in general use.

In Figs. 3 and 4 I show my invention as applied to a locomotive in whichthe cylinder 18 is located under the boiler and centrally of thelocomotive, so as not to project upon the sides thereof, as shown inFigs. 1 and 2, and in this form I provide the usual frame 19, in whichthe forward wheels 20 are connected by the crank-shaft 21, which isoperably connected to the piston-rod 22, the connecting-rods 23transmitting motion to the v rear drive-wheels 24, these drivewheelsbeingprovided with flanges instead of in the locomotive, where thecentral wheels are smooth and the forward wheels are flanged. The frame19 is of a slightly-modified construction from the other frame shown,dou- I ble bars 20 20 being employed, the bar 20 carrying the journalsor standards for the wheels, while the bar 20 is connected so as tosupport the locomotive through the medium of the leaf-springs 25, theheavy coiled spring 26 being the supporting medium between the bars 20and 20 As clearly shown in Fig. 5 of the drawings, the car is providedwith the semicircular casings 27, which project up into the body of thecar, preferably below the seats 28, but within the cars, so as toreduce, if possible, the gage of the tracks, the wheels 29 being carriedas usual and independently mounted with relation to each other, theirsupports or standards 30 being carried by the usual frame 31, which ismounted transversely under the bottom of the car and forms a platformtherefor.

In Figs.'6, 7, 8, and 9 I have illustrated in detail a constructionpreferably for various uses. These constructions may be used on thetram-cars or locomotives, and it will be seen that the platform 32, asshown in dotted lines, will assume a position with relation to thewheels so that they are swingingly supported below the axle, but abovethe tracks 31, a bottom plan view of the entire frame, with its wheels,being clearly shown in Fig. 9.

In Fig. 8 I show a means whereby the wheels can be held apart, andthough allowed to revolve independently they are connected together withvirtually a solid axle 33. In this case the ends of this axle aresocketed, as at 34, for the reception of the ends 35 of the short axles36, the heads of these ends being of a smaller diameter than the socket,so that the wheels are allowed to revolve within the same. Thisconstruction is especially desirable for locomotives, as it relieves thestrain occasioned by rounding curves and the vibration of the engine andprovides a solid structure for the support thereof.

In order that the wheels may be properly guided in rounding curves, Ihave shown various constructions in Figs. 12, 13, 14, 15, and 16 of thedrawings. In Figs. 13 and 14 and also 15 of the drawings I provide uponthe inner face of the wheels the circumferential rib 36, which isadapted to engage the curved portion 37 of the outrail 38, which isspringactuatingly mounted with relation to the supporting-plate 39 bymeans of the boltand-spring connection 40. This is especially desirablefor the locomotive or for heavy cars. WVhere the device is applied tothe forward portion of the engine, I mount the wheels as shown in detailin Figs. 16 and 17, in which the supports 41, carried by the frame 42,are in two sections 41 and 41 the same being connected together by meansof the doublepointed pin 43 and returned to its original condition bymeans of the springs 44. By this means the wheels are allowed. to turnslightly when rounding curves, so as to properly guide the locomotive orcar therearound, and thus reduce the grinding or sliding friction uponthe rails. In order to properly guide the wheel in this movement, Iconnect in the forward end of the frame 42 a braced plate 45, which isprovided with the large sleeve 46, the other sleeve 47, in which isadapted to be mounted the stem 48, carrying the yoke 49. In order toproperly cushion this yoke as its wheel 50 strikes the auxiliary rail51, I provide the spring 52, which is mounted upon the stem between thesleeves 46 and 47. The third rail or the auxiliary rail 51 is providedwith the curved abutting surface 53 and is mounted slidingly between theparallel guide-plates 54, to which the guide-rail is connected by meansof the spring-actuated bolts 55. In order to properly oil the axles ofmy improved construction of wheel, the axle is provided with the centralbore or channel 56, which is adapted to communicate with the caps orreceptacles 57 and 58, the oil being fed to the cap 57 through the cup59 and following the lines of the arrow, as indicated in Fig. 20, allthe details of these constructions being shown in Figs. 18, 19, and 20.

In Figs. 10 and 11. I have shown a new embodiment of my invention asapplied to long heavy cars as used upon steam and electric railways andin which I obviate the great difficulty in rounding the curves and alsoin distributing the weight, the three pairs of wheels 60, 61, and 62being employed. The wheels 60 and 61 and their frames are con structedsimilarly to the wheels shown in Fig. 16, except that the device forrounding the curves is dispensed with, these pairs of wheels beingmounted, respectively, at the ends of the car. The centrally-arrangedwheels 62 are both carried upon a common axle 63, the said wheels beingmounted within their individual frame-supports 64 IIC upon the usualstandards 65, the tread 66 of these wheels being of greater width thanthe treads of the wheel 61 and are flangeless or perfectly smooth, sothat as the car rounds the curves these wheels slide sidewise orlaterally upon the tread of the rail, and thus properly carry the weightof the car and provide a means whereby the central portion of the car isproperly supported, the dispensing with the flange and the widening ofthe wheel in combination with the wheels mounted at the end of the carmaking this possible.

From the foregoing description, taken in connection with the drawings,it is evident that I provide a means for mounting railwayrolling-stockvhich allows the center of gravity to be nearer the tracks,which assists the locomotives or cars in rounding curves not only forguiding them properly around the curves, but also lessening the dangerof accident by twisting or breaking the axle, which allows the weight ofthe car to be equally distributed, as a number of sets of flangelesswheels may be mounted between the end wheels, so as to equallydistribute the weight of the body of the car thereon, and I also providea means whereby the fire-box capacity of locomotives is greatlyincreased, thus improving in a great many respects the efficiency of therailway rolling-stock as now used.
